You have used ogee_spillway_design_v3_final_actual.xls for 15 years. Here is how to pivot:

Solves the standard power equation based on the specified upstream slope. Step 4: Downstream Tangent and Bucket Design

Instead of using C14 or D20, use names like Design_Head or Spillway_Length . This makes formulas readable and easier to debug [2]. ogee spillway designxls better

Hydrology inputs (inflow hydrographs, tailwater curves) are often already in Excel tables. An ogee design sheet can link directly to those ranges, creating a dynamic model where a change in probable maximum flood (PMF) automatically redesigns the spillway crest.

Ultimately, using an optimized ogee_spillway_design.xls workbook saves hundreds of engineering hours during initial design phases, allowing teams to confidently lock down sizing parameters before investing time and money into final high-fidelity software simulations.

Designing an ogee crest by hand is a tedious, iterative process. Engineers must solve the classic U.S. Army Corps of Engineers (USACE) or Bureau of Reclamation criteria, which rely on the following standard profile equation for the downstream quadrant: Step 4: Downstream Tangent and Bucket Design Instead

For a vertical upstream face, the downstream profile equation generally follows:

Most design procedures assume a vertical upstream face. However, if a slope is specified, you must adjust the coefficients. In a spreadsheet, you can implement a to automatically assign ( K ) and ( n ) values based on the upstream slope ratio:
